Economics of reusing spent nuclear fuel by Teplator for district heating applications

The Teplator is a nuclear heat-only reactor under development in the Czech Republic, which uses already irradiated spent nuclear fuel (SNF). This study aims to assess the feasibility of integrating this technology with district heating systems (DHSs) compared with other heating technologies....

The power load model for electric vehicle charging modelling and its utilisation for voltage level studies and cables ampacity in distribution grid

When electrical energy is drawn by electric vehicles from charging stations at charging process the voltage drops and increased current loading of cable lines in distribution grid occur. Inasmuch the electrical grid is insufficiently dimensioned or at large amount electric vehicles concurren...

Environmental impact and aging properties of natural and synthetic transformer oils under electrical stress conditions

Against the background of environmental compatibility and unrestricted technical usability, synthetic, and natural transformer oils are critically compared in long-term tests under high voltage using electrical and instrumental analytical methods. Synthetic alkyl esters of pentaerythrol appear to be sustai...
